Description

Technical Field

[0001] The present invention is applied in the technical field of eccentric disc rolling bearings, and particularly relates to an assembly device for an eccentric disc rolling bearing. Background Art

[0002] An eccentric bearing is a type of bearing that is not commonly used. The eccentric bearing has a simple structure and is convenient to use. It can achieve the eccentric function without an eccentric shaft, greatly simplifying the eccentric mechanism. At the same time, it saves labor and time in the machining of the eccentric mechanism, is easy to assemble, and reduces the manufacturing cost of the eccentric mechanism. It mainly includes four basic components: a connecting rod bearing outer ring, an eccentric disc bearing inner ring, a cage, and rolling elements.

[0003] Among them, the cage (i.e., the bearing cage, also known as the bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them, used to isolate the rolling elements, and usually also guides the rolling elements and holds them in the bearing. The existing assembly between the retainer and the balls is mostly manual assembly, with extremely low production efficiency. At the same time, due to the relatively high work intensity, workers are prone to fatigue.

[0004] In addition, the existing Chinese Patent Publication No. "CN111230461B" discloses a bearing assembly device capable of automatically assembling balls, which relates to the technical field of bearing processing. It is used to solve the problems that workers need to fill single balls into the retainer from the notch at a relatively slow speed, and after the workers assemble the balls on the bearing, they still need to manually rotate the inner ring of the bearing with relatively low efficiency, and during the assembly, it is necessary to fix the position of the retainer to prevent the balls from falling out of the track, with relatively slow efficiency. It includes a base; a support frame is vertically and upwardly fixedly installed at the rear end of the top plane of the base. In the present invention, since a pressure rod is vertically inserted at the front end of the lifting mechanism, a gear is fixedly installed in the middle of the wheel shaft, tooth teeth meshing with the gear are vertically and evenly spaced on the back arc surface of the pressure rod, and a handle is vertically installed at the right end of the wheel shaft. When the handle is rotated counterclockwise, the pressure rod can be moved downward through the rotation of the gear, so that the ball feeding mechanism can be docked with the bearing, and then the action of assembling the balls can be completed.

[0005] The above description has the following problems: 1. When assembling and fitting the bearing, it is necessary for workers to manually rotate the handle counterclockwise. At this time, the pressure rod is moved downward through the rotation of the gear, so that the ball feeding mechanism can be docked with the bearing, and then the action of assembling the balls can be completed. The manual operation has low efficiency, and at the same time, due to the relatively high work intensity, workers are prone to fatigue; 2. When the ball feeding mechanism moves downward to be docked with the bearing to assemble the balls, the ball feeding mechanism is likely to cause hard damage to the bearing, invisibly increasing the production cost and assembly time.

[0092] The working principle of this eccentric disk rolling bearing assembly device:

[0093] Step 1: First, place the outer ring 11 of the connecting rod bearing and the inner ring 12 of the eccentric disk bearing on the ratchet 20221. At this time, the inner ring 12 of the eccentric disk bearing is fixed by the limit projection 2041, and the outer ring 11 of the connecting rod bearing is positioned by the positioning projection 2042. The feeding notch 15 on the outer ring 11 of the connecting rod bearing is located at the top of the upper end face of the ratchet 20221. After that, the cage 13 is installed between the inner circumference of the outer ring 11 of the connecting rod bearing and the outer circumference of the inner ring 12 of the eccentric disk bearing;

[0094] Step 2: Rotate the rotating disk 324 to make the second blanking hole 325 communicate with the first blanking hole 322, and place the tank body 8 filled with balls 14 in the placing sink 7 of the rotating disk 324. After the operator pulls open the material-passing plate 323, several balls 14 in the tank body 8 sequentially enter the ball conveying channel 333 in the feeding plate 332 through the second blanking hole 325 and the first blanking hole 322;

[0095] Step 3: The operator starts the operation of Drive I 93 and Drive Assembly 203 by pressing the start / stop button 24 on the electrical control box 94 or starts the operation of Drive I 93 and Drive Assembly 203 by stepping on the foot switch 23. Drive I 93 drives the moving plate 91 to move, making the through hole 92 on it communicate with the ball conveying channel 333. At this time, the lowest ball 14 in the ball conveying channel 333 falls through the guide pipe 21 into the feeding notch 15 on the outer ring 11 of the link bearing, and the ball 14 then rolls into the ball hole of the cage 13;

[0096] Step 4: At this time, with the outer ring 11 of the link bearing stationary, the driving end of the drive assembly 203 moves forward along the horizontal direction, thus pushing the rotating disk 2021 to rotate counterclockwise, and then driving the ratchet wheel 20221 and the inner ring 12 of the eccentric disk bearing, the cage 13 and the ball 14 installed in the cage 13 to rotate counterclockwise, so that the ball hole of the next ball 14 to be installed in the cage 13 is located at the feeding notch 15 of the outer ring 11 of the link bearing. After that, the driving end of the drive assembly 203 resets and drives the rotating disk 2021 to rotate clockwise. The ratchet wheel 20221 and the inner ring 12 of the eccentric disk bearing and the cage 13 placed on the ratchet wheel 20221 remain stationary under the action of the pawl 20222. After that, the next ball is assembled, that is, Drive I 93 is started again to drive the moving plate 91 to move, making the through hole 92 on it communicate with the ball conveying channel 333. At this time, the lowest ball in the ball conveying channel 333 falls through the guide pipe 21 into the feeding notch 15 on the outer ring 11 of the link bearing. After that, the above assembly operation is repeated until all 72 ball holes in the cage 13 are assembled with balls 14, then the assembly of the eccentric disk rolling bearing is completed.
